CLO D- CRUSHER.

SJPECIFICATION forming part of Letters Patent No. 660,97 5, dated October 30, 1900.

Application filed October 27, 1899. Serial No. 735,004. (No model.)

To all whom it may concern 1,:

Be it known that I, JOSEPH SOHOELER,a citizen of the United States, and a resident of Hamilton, Ohio, have invented certain new and useful Improvements in Olod-Crushers,

of which the following is a specification;

Myinvention relates to clod-crushers; and the object of my improvement is to provide a frame consisting of two similar sections hinged together on a line with the pole,whereby two short shafts may be used instead of one long shaft, and thus secure compactness of construction, flexibility in operation, and adaptable automatically to uneven surfaces.

I 5 These objects are attained in the followingdescribed manner, as illustrated in the accompanying drawings, in which-- Figure 1 represents the plan of a clodcrusher embodying my'improvement; Fig. 2,

a rear elevation of the middle portion of the frame with seat attached; Fig. 3, an end elevation with parts in section, and Fig. 4 a perspective View of the front hinge with parts of the middle cross-bars attached thereto.

In the drawings, 5 and 6 represent the front and rear bars of the frame, each consisting of two pieces, secured at one end to the end bars 7 and at the other end to hinges 8 and 9. Said hinges are each formed with transverse depending flanges 11,150 which the corresponding ends of middle bars 10 are rigidly secured. Said middle bars are preferably formed of metal and placed edgewise vertically to cocupy a small amount of lateral space between 5 the wheels. The front end 12 of one of the said middle bars is extended beyond the front hinge to form a secure attachment thereto of the rear end of the pole l3. Stay-rod 14 is rigidly secured at one end to the pole and at the other end to the corresponding portion of the front bar, whereby the pole is rigidly attached to one section of the crusher and in the line of the hinges, as shown. Stay-rod 15 is hinged at one end to the opposite side of the 5 pole and at the other end to the front bar of the other section to facilitate the movement of the hinges.

Bearings 16 are attached to one side of the middle portion of the middle bars and are closed at one end by said bars to serve as a stop forthe end of shafts 17, j ournaled therein. The opposite ends of said shafts are journaled in bearings (not shown) that depend from the middle portion of the end bars and wherein they are retained by means of collars 18 in the usual manner. A series of metal wheels are loosely sleeved on the shafts between the bearings that either the shaft may turn in the bearings or the wheels on the shaft to lessen the friction of the parts in use. Each of said wheels is formed with lateral periph= eral projections, as shown at 21, to more effl ciently crush the clods as they are drawn over the surface of the ground.

Seat 22 is mounted at its ends on the respective sections of the frame by means of inverted stirrups 23 and 24, the former being rigidly secured at its ends to the front and rear bars of one section, the latter being hingedto the corresponding bars of the other section, both stirrups being hinged to the seat, as shown.

In this manner the seat partakes of the movement of the hinges of the frame without any straining of parts.

The increasing width of clod-crushers demanded by the trade makes their construction in sections and hinged together indispensable that they may adapt themselves to uneven surfaces and to avoid the use of a single long shaft that is frequently broken 8c in use.

Having fully described my improvement, what I claim as my invention, and desire to secure by Letters Patent of the United States,

1. In a clod-orusher, the combination with a frame, hinges bisecting the front and the rear bar thereof middle bars rigidly secured to the hinges and movable therewith in relation to each other, of a pole rigidly secured to the front end of one of said middle bars, and stay-rods connecting the pole with the front bar.

2. In a clod-crusher, the combination with a rectangular frame, hinges bisecting the 5 front and the rear bar thereof and formed with depending flanges, middle bars rigidly secured to the flanges on corresponding sides of the hinges, a pole rigidly secured to the front portion of one of the middle bars, stay- [00 rods connecting with the pole and the front bar, and a seat movably supported on the frame by means of inverted stirrups.

JOSEPH SOHOELER.
